Problems solved by technology

Polymerized proppants are spherical particles with smooth appearance formed by polystyrene through polymerization reaction. In a dry environment, they will have a strong electrostatic reaction with the metal surface and adhere to the metal surface. The instruments currently inquired are all dry sieves. extension, and the screen is made of stainless steel, so it is impossible to accurately characterize the overall sieve analysis distribution of polymeric proppants

Abstract

The invention belongs to the technical field of oil recovery engineering. A polymeric proppant automatic lifting dry and wet screening device, including a shell, a supporting frame, a vibrating screen, a water spray belt, a lifting component, a water supply component, a drying component and a control system, and the supporting frame is passed through an elastic component It is arranged in the housing, and the support frame is provided with a vibrator, and the top of the support frame is provided with a shower head; multiple sets of vibrating screens are stacked in the support frame, and multiple sets The screen aperture of the vibrating screen decreases sequentially from top to bottom; a water spray belt is arranged between two adjacent vibrating screens; the water supply component is used to supply water to the spray head and the water spray belt; the drying component Used to dry the sieved proppant. Also disclosed is a polymeric proppant automatic lifting dry and wet screening method. The application can accurately measure the particle size distribution of particles with strong electrostatic reaction, and can realize the experimental research of sieve analysis and evaluation on particles with strong electrostatic reaction.

Description

technical field [0001] The invention belongs to the technical field of oil recovery engineering, and in particular relates to an automatic lifting dry-wet screening device and method for polymer proppant. Background technique [0002] In the field of oilfield fracturing, in order to ensure the effect of fracturing, it is necessary to conduct screening analysis and evaluation experiments on proppant or polymeric proppant for fracturing. Polymerized proppants are spherical particles with smooth appearance formed by polystyrene through polymerization reaction. In a dry environment, they will have a strong electrostatic reaction with the metal surface and adhere to the metal surface. The instruments currently inquired are all dry sieves. The extension machine, and the screen mesh is made of stainless steel metal, so it is impossible to accurately characterize the overall sieve analysis distribution of the polymeric proppant. Contents of the invention [0003] The purpose of t...
